Hard Drive Activity LED Pins
Pins 1 and 3 can be connected to an LED to provide a visual indicator that data is
being read from or written to a hard drive. Proper LED function requires one of the
following:
• A SATA hard drive connected to an onboard SATA connector
• A PATA hard drive connected to an onboard PATA connector
• Intel Z-U130 USB Solid State Drive (or compatible device) connected to one of the
front panel USB headers
Reset Switch Pins
Pins 5 and 7 can be connected to a momentary single pole, single throw (SPST) type
switch that is normally open. When the switch is closed, the board resets and runs the
POST.
